GEORGE A. YOULDEN, OF PROVIDENCE, RHODE ISLAND.

WINDOW-SCREEN.

SPECIFICATION forming part Of Letters Patent No. 624,418, dated. May 2,1899.

Application filed February 24, 1899. Serial Not 706,676. (No model.)

T0 at whom, it may concern:

Be it known that I, GEORGE A. YOULDEN,'

curely exclude flies and other insects from the rooms; and a furtherobject of the invention is to facilitate the operation and adjustment ofthe screen, as well as its ready removal; and to these ends theinvention consists in the peculiar and novel construction of the screenand the ways in which it slides, as will be more fully set forthhereinafter.

Figure 1 is a front elevation of a windowframe, showing myimprovedscreen and ways connected therewith. Fig. 2 is a vertical transversesectional view of the windowframe, showing my improved screen inconnection with the ways. Fig. 3 is a vertical transverse sectional viewof the windowframe, showing the swinging portion of the ways by means ofwhich the insertion and removal of the screen is facilitated. Fig. 4 isa horizontal sectional View of the windowframe, showing the screen inplace. Fig. 5 is a sectional view of the window-sill and the lower endof the ways, showing a spring-latch by which the lower end of the waysis heldin place. Fig. 6 is a sectional detail view of the screen,showing one of the rollers by which the screen is guided and supported.Fig. 7 is a transverse sectional view of Fig. 6.

Similar marks of reference indicate corre sponding parts in all thefigures.

In the drawings, a a indicate the sides of the window-frame; b, thesill; c c, the grooved ways by which the screen is guided and supported;c, the hinged part of the ways; (1, a top and d a bottom rail connectingwith the two ways on the sides of the window-frame; e, the frame of thescreen, provided on its four sides with projecting flanges e e,overlapping the joint and part of the ways; f, the wirecloth or othermaterial of the screen; g,

grooved rollers provided with the T-shaped rubber rings g and journaledon the screws 9 Two of these rollers are secured in recesses formed oneach side of the frame a of the screen, as is indicated in Figs. 1 and2. The upper parts of the ways 6 and the rail (1 are firmly secured tothe frame. The lower parts a c of the ways and the bottom rail cl arepivoted on screws 0 c screwed into the frame, as shown in Fig. 1, sothat the lower ways, with the screen, may be swung into the inclinedposition shown in Fig. 3, when the screen may be removed or inserted.The rollers g, covered with the elastic rubber rings 9, form the guidesfor the screen. They run in the grooves of the ways 0, as shown inFig.7. They are journaled on the screws g g*, which are secured in theframe of the screen in such positions that the rubber rings g onthe-roller g are compressed sufficiently to prevent rattling andpreferably so that the screen will be supported when in the raisedposition and maybe removed without the exertion of greatforce. r

To secure the swinging ways 0 c and the rail (1 in the verticalposition, I place into the sill b one or two of the spring-latches,(shown in Fig. 6,) consisting of the metal tube h, the bolt h inscrew-thread engagement with the semispherical button h supported on thecoiled spring h and secured to the rail 01', the plate It, provided witharecess corresponding with the button h so that the coiled spring Itwill force the button 72. to enter the recess and lock the rail 01 andthe swinging ways 0' in the required position, while a'suftlcient strainon the rail (1 willdraw the rail over the rounded end of thespring-pressed button.

A window fitted with my improved ways and screen presents a neat andfinished appearance. The screen, when desired, maybe readily removed orplaced in any desired position, and the overlapping flanges c e willcover and protect the joints, so as to prevent the entrance of insects.When used to cover the opening formed by the raising of the lowerwindow-sash, the upper flange extends over part of the lower rail of theraised lower sash and over the lower rail (1, and when the upper sash islowered the raised screen will cover part of the upper rail 01 and partof the upper rail of the lower sash. The screen may be locked by the useof an ordinarybolt 11, preferably sunk into the Wood of the frame.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination with a window-frame, of the upperrail d, and the grooved ways 0 a secured to the window-frame, the rail dand the ways 0 c pivotally secured to the window-frame, and means forsecuring the rail d and the swinging ways 0' c in alinementwith the ways0 0; whereby the screen may be raised and lowered, as described.

2. In a window-screen, the co1nbination with the upper rail 01 and thegrooved ways 0 a secured to the window-frame, the swinging ways 0' c andthe lower rail 01- pivotally secured to the window-frame, of the frameof the screen, flanges projecting from the four sides of the frameoverlapping part of the ways and adapted to overlap part of the upper orlower rails, the rollers g g grooved peripherally and journaled in theframe, and the rubber rings g g; whereby the screen may be raised andlowered, as described.

3. In a window-screen, the combinationwith grooved, vertical wayssecured tothe vertical sides of the window-frame, of the frame 6 of thescreen, the projecting flanges e, the screws g 9 the grooved rollers gjournaled on the screws, and the rubber rings g of T-shapedcross-section; whereby the screen may be moved and supported and thejoints overlapped to prevent the entrance of insects, as described. 7

4. In a window-screen, the combination with the ways 0 0 and the rail (1secured to the window-frame, the ways 0' c and the rail 01' pivotallysecured to the window-frame by the screws 0 c of the screen-frame e, theprojecting flanges e, the rollers g journaled in the frame, the rubberrings g g on the roller, the plate 71 on the rail 01, and thespringpressed button h whereby the screen may be used to cover the upperor the lower part of the window and the screen may be readily removed,as described.

In witness whereof I have hereunto set my hand.

GEORGE A. YOULDEN.
